What is the smallest number with 2 3 4 and 7 as factors?
Here we have to calculate the LCM of 1,2,3,4,5,6,7,8,9,10. LCM=2^3 * 3^2 *5*7=2520. Therefore smallest number which is divisible by 1,2,3,4,5,6,7,8,9 and 10 is 2520.
What is the smallest factor of 5?
16 is the smallest number with exactly 5 divisors. 12 is the smallest number with at least 5 proper divisors.
What is the smallest whole number that is divisible by 5 and by 3?
15 is the smallest whole no. So, 3 & 5 are prime numbers.
What is the least common multiple of 3 and 5?
15
Answer: LCM of 3 and 5 is 15.
What is the factor of 7?
Solution: The factors of 7 are 1, 7, and factors of 7 are 1, 7. Therefore, the Least Common Multiple of 7 and 7 is 7 and the Greatest Common Divisor (GCD) of 7 and 7 is 7.
What’s the smallest number with 3 different prime factors?
30
The three smallest prime numbers are 2, 3, & 5. When we multiply 2*3*5 weget 30. Answer: 30 is the smallest number that has three different prime factors.
What is the smallest number that has the factors 7 and 9?
63
63 is the least common multiple of 7 and 9 .
What is the smallest number with 7 factors?
Explanatory Answer | GRE Quantitative Comparison Question 1 So, any number that has 7 factors will have p = 0 and q = 6. i.e., the number will have only one prime factor. 2 is the smallest prime number. So, the smallest number that will have 7 factors, N = 26 = 64.
What is the smallest whole number with all the factors 3*5*7?
3: Prime. 5: Prime. 7: Prime. So, the smallest whole number that has all of 3, 5 and 7 as factors would be. the product of the numbers. So, 3*5*7=105. Suppose,the numbers were not all prime.
What is the value of 3*5*7?
7: Prime. the product of the numbers. 3*5*7=105. Suppose,the numbers were not all prime. Take 2, 6 and 8, for instance. Let N be the smallest number with 2, 6 and 8 as factors.
How do you find the factor pair of a whole number?
Start with the number 1 and find the corresponding factor pair: n ÷ 1 = n. So 1 and n are a factor pair because division results in a whole number with zero remainder. Do the same with the number 2 and proceed testing all integers (n ÷ 2, n ÷ 3, n ÷ 4…
How do you find the factors of a large number?
To calculate the factors of large numbers, divide the numbers with the least prime number, i.e. 2. If the number is not divisible by 2, move to the next prime numbers, i.e. 3 and so on until 1 is reached. Below is an example to find the factors of a large number.
